RESEARCH AND DEVELOPMENT OF BIOMETRIC METHODS

Identification systems play a very important role in today's society. Complex security requirements have prompted experts to explore ways in which biometrics can be used to identify customers. In this article, the concept of biometrics, biometric data and its variants are considered. The purpose of the article is to study the process of identification, to produce its improved version and introduce innovation. Thus, the following points served as a research method:- Initialization.- Fitness functions.- Unclear clusterleu method.The results showed that the advancement of biometric systems and biometric sensors can improve the identity and prevent others from using the identity, the system has great potential to improve the security and accuracy of the biometric technology system. Biometric systems increase the security of users, as well as ensure accuracy in the identification of personal identity. Thus, the accuracy of the proposed method is compared with four modern methods. The comparison shows that the proposed approach provided a high accuracy of about 99.89% and a low error rate of 0.18%. It turns out that there is real potential for the integration of fingerprints and iris biometrics in many subjects with the appropriate assessment.

Autonomous IoT System Security Capability: Pushing IoT Security to the Edge

Complex systems of IoT devices (SIoTD) are systems that have a single purpose but consist of multiple IoT devices. These systems are becoming ubiquitous, have complex security requirements, and face a diverse and ever-changing array of cyber threats. Privacy and bandwidth issues will prevent all data from these systems from being sent to a central location, so these systems cannot completely rely on a centralized cloud service for their security. The security of these systems must be provided locally and autonomously. In this paper, we describe the capability to address this problem, explain the system specifications, present our work to enable SIoTD, and show initial results of a novel edge-based machine learning application to build this capability.

CREDIT FOR SMALL AND MEDIUM ENTERPRISES: A STUDY ON KHULNA CITY CORPORATION, BANGLADESH

Small and medium enterprises (SMEs) often face challenges in getting access to finance form banks and other financial institutions. This study tries to trace out such challenges faced by the SMEs of Khulna city in Bangladesh. The study follows stratified random sampling technique to select 60 interview respondents in the city. The study findings indicate that high rate of interest, longer loan processing time and complex security requirements are the three prime obstacles faced by the SMEs in getting access to finance. These obstacles hinder the development of SME sector. This study also tries to trace out the influence of credit on performance of SMEs through running multiple linear regressions. Profit and sales are considered for measuring performance of SMEs. The regression results indicate that firm size and credit have statistically significant positive influence on profit and sales of the SMEs. The firms having larger amount of credit are enjoying more profit and sales compared with those having smaller amount of credit. Hence, this study recommends for removing obstacles faced by the SMEs in getting access to finance. More specifically, this study recommends for decreasing interest rate, reducing loan processing time and simplifying security requirements for getting loan by the SMEs from banks or other financial institutions. Such initiatives will contribute to simplify the process of getting access to finance for the SMEs which will ultimately help to improve performance through boasting sales and profit.

A comprehensive and critical analysis of TLS 1.3

The TLS 1.3 protocol is a new and an enhanced version of TLS and TLS 1.2 protocols. This protocol assures a secure communication between the client and the server over the internet, that gives an end-to-end security to the seamless cyber-physical system communication. Most of the browsers which have been using TLS 1.2, compromises on several security constraints. In order to address this issue, the TLS 1.3 is defined by the IETF group through multiple improved iterations, which in turn empowers the TLS 1.3 to satisfy complex security requirements for robust communication. According to several research studies, we identified the various scenarios that ascribe the performance of TLS 1.3, its advantage over TLS 1.2 and also the scope of improvement in TLS 1.3 as it is still evolving. As per various research, TLS 1.3 possesses several shortcomings in the areas of Zero Round Trip Time (a.k.a 0-RTT), Fault Tolerance, and Forward Secrecy which leads to security issues. In this paper, we thoroughly examine the shortcoming and scope of improvement in TLS1.3 as presented by various researchers and also study the error alerts defined in it. We propose the requirement of three new error alerts in the current version of TLS 1.3 which are Cookies Extension, Deadlocked Connection and Integrity Algorithm Storage in order to have a smooth communication.

Enabling Fog Complex Security Services in Mobile Cloud Environments

The security infrastructure in modern mobile cloud relays on a set of atomic security services like key distribution, and authentication services which are mostly deployed at the fog. A mobile node may provide a simple or an atomic security service. Complex security services are obtained by coordinating several atomic services at different nodes. In mobile fog environments, the availability of such services for the mobile nodes at the edge straggles challenging nature of the environment and then service availability is deeply affected. Complex security requirements require available several atomic services at the edge and fog levels. So, increasing atomic service availability is vital and enhances security features between the fog and the edge. In this work a proactive complex security service replication protocol for increasing availability of fog security services is proposed. The protocol is able to manage proactively replicas whenever they are requested. It is aware of the distributed resources at the edge nodes. Using an extensive simulation analysis, the protocol performance shows a better achieved availability and reasonable response time for complex security services in different configurations.

Complex security requirements have led experts to explore ways in which biometric data can be used to identify user identities. This paper presents an overview of biometric standards and methods which can be used to identify users in biometric systems, and therefore to protect information and communication systems. Methods: This paper deals with the problem of standardization in the field of biometrics. The first part of the paper presents concrete examples of the most widely used biometric standards. The second part of the paper gives an overview of the most used biometric methods. Results: The obtained results show that the development of biometric systems and biometric sensors contributes to better protection of identity from misuse, because biometric technologies have great potential for improving the security and accuracy of system operation. Biometric systems improve the security of users and also provide much greater precision in establishing identity. Conclusion: The development of biometric standards should focus on their interconnectivity, as well as on increasing connectivity with other IT standards.

Securing the "Bring Your Own Device" Paradigm

The current mobile application distribution model cannot cope with the complex security requirements of the emerging bring your own device (BYOD) paradigm. A secure metamarket architecture supports the definition and enforcement of BYOD policies and offers a promising prototype implementation tested under realistic conditions. The Web extra at http://youtu.be/0hEJoGhzczs is a video slideshow discussing BYODroid, an implementation of a secure meta-market dealing specifically with the Android OS. A secure meta-market is an extension of the current mobile application distribution paradigm supporting the definition and enforcement of Bring Your Own Device policies on personal devices. BYODroid automatically retrieves application packages from Android stores and formally verifies whether such applications comply with a given formal BYOD policy, thereby allowing the installation of policy-compliant applications only. The presentation briefly explains the idea behind the secure meta-market model and provides an experimental assessment of BYODroid.

Comparing and debugging firewall rule tables

Firewalls are one of the essential components of secure networks. However, configuring firewall rule tables for large networks with complex security requirements is a difficult and error prone task. A method of representing firewall rule table that allows comparison of two tables is developed, and an algorithm that determines if two tables are equivalent is provided. (That is the set of packets that are permitted by the two tables are the same.) How such algorithm can assist system administrators to correctly implement organisational policy is discussed. The proposed approach is implemented and the results of the experiments are shown.
